tach

Writing Benchmarks

Benchmarks are pretty easy, I'll explain a simple example

Tach.meter(4) do
tach('first') do
sleep(rand)
end
tach('second') do
sleep(rand)
end
end

The optional argument to meter tells it how many times to run each tach (it
defaults to 1) Each tach should have a name, so you can recognize them in
the results Then inside the tach block you should specify the code you care
about comparing. The name of each tach will be displayed as it starts

For things requiring more complex setup you can make them do their own
iteration, for instance:

Tach.meter(4) do
tach('complex') do |count|
duration = rand
count.times do
sleep(duration)
end
end
end
